Objective: Aldosterone-producing adenomas (APA) are a major cause of primary aldosteronism. Somatic mutations explain the excess aldosterone production in the majority of patients with APA with mutations in KCNJ5 encoding a potassium channel the most prevalent in most reported populations. Mechanisms driving cell proliferation are largely undefined.Design and method: Quantitative transcriptome analysis using RNA-seq was used to identify differen...

Background: Aldosterone-producing adenomas (APA) are a major cause of primary aldosteronism. Somatic mutations explain the excess aldosterone production in the majority of patients with APA with mutations in the potassium channel KCNJ5 the most prevalent. In contrast, mechanisms driving cell proliferation are largely unresolved.Objective: To identify genes that modulate cell growth in APAs.Methods: Quantitative transcripto...

Background: Primary aldosteronism (PA) is mainly caused by unilateral (unilateral PA) or bilateral aldosterone-producing lesions of adrenals (bilateral PA). Accumulating findings suggest distinct metabolic profiles between patients with unilateral and bilateral PA. However, the link between the metabolic features and histopathologic findings of adrenals from patients with PA remains largely unknown.Objective: To characterize metabolic profiles with a foc...

Background: Primary aldosteronism is commonly caused by an aldosterone-producing adenoma (APA). Somatic mutations in the KCNJ5 gene (encoding an inwardly rectifying potassium channel) are found in around 40% of APAs, KCNJ5 germline mutations cause familial hyperaldosteronism type III. The role of KCNJ5 mutations in excessive aldosterone production is established but their role in cell growth is unclear.Objective: To study the e...
